Origin Version (Select Help-->About Origin): 7.5SR6 Operating System: WinXP SP2
Although I got the most recent Origin version and I set <Margin Control> to "Tight", exported PDFs are not clipped exactly. There remains some white space around the graph. This is particularly annoying when trying to align graphs horizontally to page borders. Is there a way to make the PDF filter clip EXACTLY?
Even with Tight as the Margin Control setting there will still be a zero, one or two pixel border around the graph - depending on the object types at the edge.
Note that Text Objects are treated as if they had their backgrounds on even if they are not, so there may be more than two pixels in these cases - particularly the lower limits of text objects.
If the problem you are describing is more than these few pixels then do send us a project file.
